Q1. (a) Calculate the magnitude of the gravitational force exerted by Venus on an 80 kg human standing on the surface of Venus. (The mass of Venus is 4.91524 kg and its radius is 6.1107 m.)

(b) What approximations or simplifying assumptions must you make in the calculations? (Note: Some of these choices are false because they are wrong physics!)

Q2. An 846-N sled is pulled a distance of 193 m. The task requires 1.70 x 10^4 J of work and is done by pulling on the rope with a force of 124 N. At what angle is the rope held?
